TRACE-HOLDER.

To all whom t may concern; 1 v

`Be itlmown that we, ROBERT E. GRUWELL and AUGUST WIEBKE, citizens ofthe United States, residing at Miles City, in thecounty of Custer and State of Montana, have invented certain new and useful Improvements in Trace-Holders and we do hereby declare the following to be a full, clear, 'and eXact description of the invention, such as will enablel others Skilled in the art to which it appertains to make and use the same.

Our-invention has for its obj ect to provide an improved trace-holder for preventing accidental separation of the trace from the end of a whiflietree.

'Io this end the invention consists of the" vnovel devices' and combinations of devices hereinafter described and defined in the the end of a whiflletree.

In the accompanying drawings, which illustrate our invention, like characters indicate like parts throughout the several views.

Figure 1 is a plan view showing by dotted lines one end of a whiffletree and showing our improved trace-holder applied thereto. Fig. 2 is a side elevation of the trace-holder shownin Fig. 1. Fig. 3 is a ltransverse section .taken on the line w3 :r3 of Fig. 1. Fig. -4v is a longitudinal section taken on the line m4 of Fi 1. Fig. 5 is a plan view. illustrating a mo ied form of the trace-holder; andFig. 6 is a side elevation of the parts shown in Fig; 5, some parts being broken away. v

Referring to the construction illustrated` in Figs. 1 to 4, inclusive, the numeral 1 indicates a Whiffletree, the same being shown by dotted lines only.- The. numeral 2 indicates the body member and the numeral 3 the Supplemental sectionof the improved trace'holder. The body member 2 is provided with a lagscrew 4, which is adapted to be screwed intov The members 2 land 3 are, as shown,'provided, respectively, with rectangular perforations 5 and 6, the former of which is lar er than the latter. On the opposite sides ofDr the slots 5 and 6 the members 2 and 3 are formed with half-seats?, that register with each other and are adapted to receive and hold'the t'runnions 8 ofan annular lock-hook 9. The body of the lock-hook 9 is approximately rectangular and is adapted to move from one position to another within the rectangular perforation 5 ofthe member 2.

the member 3, asbest shown in Figs. 1 to 4,

inclusive. vWhen the hook-10 is engaged, as

shownin said views, the members'2 and 3 are interlocked outer ends, being then` passed through a perforation in the inner end of the member 3 and the coincident perforation in the .member 2. The

members are rigidly secured together, and the lock-hook 9 is irremovably held 'in working position, but pivoted to the said two members. As preparatory toapplying the trace to the end of the whiflietree-that is, to the body made up of the members 2 and 3-an angular lock-piece is turned into the position indicated in Figs. 1 to 4, inclusive, and the trace is then forced inward o n the said body until it passes beyond the lock-piece. Under this movement of the trace the lock be moved pivotally Vthrough an'angle of about ninety degrees, but should thereafter be turned back into the position shown in the said views, and the trace being forced outward against the upturned end of said lock will be securely held against acciand clamped together at their dental displacement.

In the construction illustrated in Figs. 5

and 6, the body member 12 of the trace-holder is provided at its outer end with a socket which receives the reduced end of the whiflietreel 1a. The screw 13 then being passed vthrough the inner end of the said member 12 and secured intothe whiiiletree, the two parts are interlocked and firmly united. The

member .12 is provided'with 4a rectan ular perforation or lock-seat 14, in which the ockpiece 9 is mounted to work, and the trunnions 8 of said lock-piece are s eated in notches 15 formed in the member 12 and opening at the undersurface thereof in such manner that the lock-piece may be readily removed when,

the rivet 11 or' similar device but only when, the member v12 isremoved from the whiffletree.

The device above described,while especially designed for application to the end of a w theless` adapted for use for other purposes and may, for instance, be applied` to the end` of a wagon-pole for use to hold the neck-yoke. The device is of small cost and in practice has etree for a use as a trace-holder, is neverv bers are secured together, substantially as described.

In In testimony whereof We afhx our signatures in presence of' Witnesses.
